This document discusses cross-platform mobile development using Eclipse. It covers building mobile apps that can run on countless devices across different platforms like Java, C#, and Objective-C. It provides code samples for building a speakers list mobile app using these languages. It also provides an overview of key aspects of building mobile apps like views, cells, navigation, entities, and content providers.
